I am interested to hear opinions regarding the two brands of airbags, Poly-air and Coil-rite (Firestone). Who has what, and any issues with them. I can't imagine them differing too much, so lets hear about any trials or tribulations. I will be fitting a pair to my trusty 1994 Pajero just to relieve the rear springs while towing. It is amazing how much extra goes the camper in the older we get.

Hi James, I have had both and can not find any thing between them. one lot for 6 years and the other for 5 years.
And as far as putting more in as we get older, I work on the plan the only thing different between going away for one week and 10 weeks is the amount of food you take.

cheers Shane.

Hi James

I fitted a pair of air lift 1000 (same as poly-air) to my NL pajero easy to fit and it shaw makes a difference to the ride and weight distribution. I purchased mine for TRUCKSPRING.COM in USA. a lot cheaper to purchase and have posted out to AUS than buying local.

When I looked around I chose the Firestone as they seemed to be sealed better and came well reccomended.Ihave them on my Troopy for three years with no problems.I think both brands are good but make sure the installation is done properly as a slight leak in the air lines will show up right away.They certainly make a BIG difference and should hold the pressure equally on both sides for a long time if installed correctly.

Firestone bags are much more heavy duty and have a higher PSI rating.They also cost near double.
Poly Air bags are a simple sring helper installed either in the coil or between the spring and chasis.They have a lower PSI rating.
Ive had two sets of Poly Airs in differant vehicles and thought they were brilliant.Highly reccomend them.Just remember as they are a lighter construction, pump them up to their max. psi rating(around 35 PSI from memory) while the vehicle is empty and then adjust accordingly once loaded.

Nick, I think you are talking about the lighter duty red PolyAir bags and not the PolyAir black bellows type which are heavier duty with a recommended maximum pressure of 100 PSI. I am running the black ones now in a 'Cruiser with a heavy slide on camper and they are great. Previously I ran the red ones and found they were not quite up to the task, the coil springs distorted and then the bags blew but only after a lot of hard Ks.

The red Poly-air are fine for the average car for which they are designed but you will need the Black air Bellows from Poly-air for your Paj.

Yep - had the red Poly Airs inside the Jackaroo's rear coils for years - fitted them myself - never an issue - 5 to 35 psi was the range as I recall. Bought them direct from Truckspring in the US - landed on my doorstep, the all up $ were about 50% of the cost here. If interested, they have a comprehensive site and you should be able to exactly ID your vehicle and the kit number.

I have decided to go with Firestone Coil Rite air bags. After seeing them I think that the air inlet design is better than the Poly Airs. I purchased mine from the NSW distributor, All Air Suspension in Meadowbank, Sydney, and saved $50 retail over the Poly Airs. They made sure I had the correct bags for my 65mm rear lift and the service was excellent. Highly recommend them.
